Exploring compactified HEIDI models at the LHC
ABSTRACT Models with multi-scalar Higgs sectors inspired by a higher-dimensional setup
are interesting alternatives to the Standard Model because, although they have
a Higgs sector which gives mass to the W and Z gauge bosons as well as the SM
fermions, this Higgs sector is potentially undiscoverable at the Large Hadron
Collider or shows considerable deviations from the Standard Model Higgs sector.
We investigate a compactified version of such models and study its
phenomenology in the "golden" four-lepton channel at the LHC in areas of
parameter space compatible with electroweak precision observables.
